This isn't exactly a difficult boss (not even a boss, actually), but the most fun battle I've EVER seen HAD to be in Zelda 64. At some point, when you're adult Link, in the first dungeon (forgot the name... it's the forest one) you have to fight two Stalfos. I think that was the greatest swordfight I've ever seen!
While I'm on the subject, I never fished the darn game. I'm stuck in the aforementionned temple at this point where you have to assemble 4 blocks together to make a ghost's picture or something. For some odd reason, when I slap 'em together, sometimes they don't move, sometimes they actually turn out right, but nothing happens. I know I'm supposed to fit the blocks so they do that face on the wall, but is there a special way I have to do this? This thing's kept me stuck in the same place for way too long now And while it might not be a boss, it's hard. Or rather, cheap...
